🚫 Why we're not a VIP signal channel →
🚫 Differentiation

Not a VIP channel · not an offshore robot

The niche is flooded with Telegram signal channels, unregulated "AI robots" and €4,000 academies selling smoke. We're on the opposite side — every claim is verifiable.

❌ VIP Telegram channels

Leveraged forex/gold signals. Public preview hidden so you can't count the losses. Unregulated. Affiliated broker that gets paid on your volume.

→ Us: regulated IBKR broker (SEC/FINRA/CNMV). Verifiable statement.

❌ Opaque AI robots

"AI advanced algorithmic trading" with no technical disclosure. No reproducible backtest. No auditable code. Vanity metrics ("78% accuracy").

→ Us: declarative rules based on citable academic papers. Reproducible backtest with fixed seed.

❌ High-ticket academies

€2-6k course after a "free call" with a sales rep. Inflated metrics ("+€60M managed by students"). No real software product.

→ Us: self-serve product with a 60-second demo. No call. No hard closing.

Regulated broker · reproducible backtest · auditable code · public equity curve · ad-free · no leveraged CFDs. The antithesis of the scam. Verifiable line by line.

Frequently asked

FAQ

Does the demo close on its own? Can I come back?
The demo is active 7 days from signup. You can come in as many times as you want within that window. Every time you log out, data resets to the original example (perfect for testing flows without dirtying it). After 7 days, the account is automatically deleted.
What happens with my personal data?
We only keep name and email (minimum needed to verify) and optionally phone and how you found us (to improve the product). Nothing else. The financial data you enter in the demo is wiped on logout. When your demo expires (7 days), the account is deleted, but we keep the lead in DB for no-spam marketing (you can request deletion any time at contacto@petrios.app).
Is it a commercial app? Will there be a subscription?
Full registration is currently invite-only (family and friends). We're in a validation phase with real users before deciding the commercial model. If you want to be on the list when we open public registration, the demo is the most direct path — we'll notify you by email.
Are my financial data secure?
The app runs on a dedicated VPS (no multi-tenant cloud), the database is local SQLite with encrypted daily backups, authentication uses PBKDF2-SHA256 and Open Banking credentials are encrypted with Fernet AES-256 before storage. We don't use external services that see your financial data (Google Analytics, tracking, etc.).
Where does market data come from?
From several sources in cascade, each for what it does best: Finnhub for analyst consensus, earnings dates, surprises and fundamentals; FRED (St. Louis Fed) and the Fed's official calendar for CPI, jobs, GDP, PCE and FOMC dates; Alpaca (IEX feed) for real-time prices; and Yahoo Finance as a fallback for everything. Every value carries its source and freshness; if a source fails, the last known value is served and flagged as stale. The robot knows what is missing before it decides, and you can see it in the "Data quality" panel.
Can I connect my broker directly?
Yes. Interactive Brokers (live and paper, via IB Gateway) and Alpaca are integrated: orders, positions, equity and a daily reconciliation that compares what the broker says with what the app says and flags any difference. For banks, Open Banking PSD2 (Salt Edge) with a review queue: no transaction is booked without your confirmation. Excel import and PDF statements from CaixaBank and Bankinter too. DEGIRO and Trading212 have no open API: they are imported by file.
How does automatic Spanish IRPF tax work?
Every sale is matched to its purchase lots by FIFO (mandatory in Spain), converting each leg to euros at the exchange rate of its own date, as the tax agency requires. It applies the two-month rule (a loss with a repurchase within ±2 months is deferred until you sell what you bought back), keeps dividends with their withholding at source apart, and gives you the figures ready for boxes 0327 / 0328 (gains and losses), 0588 (deferred losses) and the dividend block, plus warnings for the Modelo 720 and D-6 thresholds.
Is it multi-user? Can my partner use it too?
Yes. Each user has their own isolated portfolio and wealth. An admin can register multiple users on the same instance (ideal for families). Data is NEVER mixed between users.
What does the decision engine rely on? Is it magic AI?
No. Engine v3 applies declarative rules based on published, citable academic papers: 12-1 month momentum (Jegadeesh & Titman, 1993), low-volatility premium (Ang et al., 2006), Amihud illiquidity measure (2002), Post-Earnings-Announcement-Drift, and deterministic macro vetoes (FOMC/CPI/NFP). Each rule has its own weight, is individually editable, and explains why each recommendation was issued. No black box, no "AI says buy".
Do you have a reproducible backtest? Can it be verified?
Yes, with a difference that matters: the backtest runs the same engine that trades live (same rules, stops, trailing and exits), not a vectorised approximation. The four profiles (ECO/NORMAL/SPORT/TURBO) are calibrated with that engine over a fixed universe, and the result is published inside the app with its date, universe and declared approximations: if a profile has not beaten the S&P over the period, you will see it written. We prioritise Calmar over Sharpe ("don't lose money" before "beat the market"). For quick exploration there is also a vectorised lab, labelled as indicative.
And the real executor? Does it work with an actual broker?
Yes, with IBKR (Interactive Brokers) via ib_insync and with Alpaca via REST API. Both with Fernet AES-256 encrypted credentials. IBKR trades on a real account regulated by SEC/FINRA/CNMV (Spain). The robot works in slots: each slot is one broker, one mode (live, paper or shadow) and one risk profile with its own limits. Every operation is audited, with daily reconciliation between broker positions and the app.
What stops the robot from losing a lot of money on a bad day?
Guardrails that do not depend on you watching: a daily drawdown limit per slot (with a hard cap on the live account) that pauses the slot when reached, position-size and open-position limits, stop-loss and trailing on every trade, a buy veto on CPI, jobs and FOMC days (official dates, not estimates), a veto when earnings are imminent and a regime filter when the S&P trades below its 200-session average. The watch panel shows you in five seconds what is paused, what is exposed and which data is missing. None of this guarantees gains: it guarantees a bad streak is cut short.
How do you differ from VIP signal channels or "AI robots"?
Three pillars: (1) regulated broker (IBKR SEC/FINRA/CNMV) vs affiliated offshore brokers that profit from your losses; (2) reproducible backtest vs opaque "AI advanced algorithmic"; (3) public track record with equity curve from a real account vs channels that hide their message preview. Also: cash equities only — no leveraged CFDs. Not a single cent of our roadmap goes to leveraged forex/gold.
